DAYS 1-5 (APRIL 18-22)
Low pressure moves into the Great Lakes today and its warm front to our south spawns a new low pressure area, but a ridge of high pressure holding on to the east will block it from moving completely across our region, with a blanket of clouds and some areas of light rain being about the worst we see. Clouds hang on during Friday as the new low gets pushed away to the south. Upper level low pressure will finally move eastward across the Northeast later Friday into the weekend, with the old surface low dragging a cold front and secondary trough through our region between Friday night and Saturday afternoon. This will be good for a few rain showers, then we’ll clear out for the most part for the second half of the upcoming weekend. Another low pressure system to our south will spread more clouds into the area on Monday, but right now I expect any rain from that system to stay well to the south.
